Preservatives of shampoos prevent bacterial contamination, and include sodium benzoate, parabens, EDTA, DMDM hydantoin, and tetrasodium EDTA. Moreover, most shampoos contain other ingredients like colors, perfumes, pearlishing agents, moisturizers, such as natural oils and fatty acid esters and humectants, like glycerin and sorbitol.

After micro-CT analysis, femoral neck samples were decalcified for 20 days using a mixed solution of 10% tetrasodium-EDTA and 4% phosphate-buffered formalin at 4 °C. Following fixation, the femoral neck was embedded in paraffin. Sections of 5 µm thickness were cut on a microtome, placed on charged slides, and dried overnight at room temperature before staining. The sections were dewaxed in xylene, rinsed with graded alcohol into water, and stained with the following: Harris hematoxylin, differentiating solution, bluing solution, and eosin Y solution (all from American Master Tech Scientific Inc., Lodi, CA, USA). The hematoxylin and eosin (H&E)-stained bone sections were used to quantify trabecular bone area and the number of osteoblasts and adipocytes. Histologic measurements and images were obtained under a microscope in five randomly selected fields. Blind cell count was done by JX and ZL. The staining area of the trabecular bone was analyzed using the Image-Pro Plus 6.0 software (Media Cybernetics, SilverSpring, MD, USA).
